Versuchsvorschrift

Sodium hydride (60% in mineral oil, 6 mg, 0.16 mmol) is added to a solution of 4-(2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-1,2,3,4,5,6,7,8-octahydroquinazolin-4-yl)-3-methylbenzonitrile (example 55, 60 mg, 0.13 mmol) in acetonitrile (3 mL), and the mixture is stirred at room temperature for 20 min. Methyl idodide (16 μL, 0.26 mmol) is added, and the mixture is stirred over night, diluted with N,N-dimethylformamide (1 mL) and purified by preparative HPLC (Waters Xbridge™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 13 mg; ESI mass spectrum [M+H]+=440; Retention time HPLC: 0.65 min (X012_S01).
